"Robot Vacuum Only" Parking Sign (Manual & Automatic Multicolor) - for Roborock, Ecovacs, Roomba, etc.

"Robot Vacuum Only" Privileged Parking Sign

This nifty little sign stands roughly 37cm (14.5") tall, which just looks like perfect scale when placed next to your vacuums charging station.

The longest part is 20cm (7.8"), still fitting virtually any entry level 3D printer bed!
And if you're rocking a Prusa Mini or comparable machine, there's a shortened version of that part at 17.8mm (7") included as well!

It prints in 5 Parts that can easily be glued together using generous gluing surfaces and interlocking indexing notches - but as they say: A picture is worth a thousand words.
So check it out for yourself in this GIF!

The signs can be printed using either multimaterial printing, separately printed inlays or manual filament changes  - simply grab the corresponding files for your usecase.

It prints in four colors - Black, White, Blue & Silver.
See the attached images or read below for details on where to put what color.

Print Orientation

All parts are already oriented the way they are intended to be printed!

Multi Color Printing (Three Ways)

Regardless of whether you have a state-of-the-art printer with an attached filament changer or a machine that struggles with straight lines, you WILL be able to print this in all its glory.
I've designed three ways with descending level of “intricacy” and precision required from your machine. Pick the first way your printer can handle and you'll be off to the races!

1. Multi Material Printing (MMU, AMS, ACE, etc.)

Simply grab the files labeled “Multimaterial” and paint them in your slicer of choice.
To make that easier, I've named every component for its designated color and prr-colored them in fusion… Orcaslicer and derivatives should be able to consistently ‘grab’ and match the colors from that.

I've also included a file with all parts pre-arranged on a 180x206mm footprint.

2. Single Color with Inlays

With the inlay route, the sign parts come with different offsets to accomodate the tolerances your printer can manage. Download the version best suited for you. This should be your go-to for non-multimaterial printing, as it gives the cleanest results.

Optionally, you can set one manual filament change from white to silver when the back of the signs changes into the pole part.

Be sure to print Sign Park_Offset-0.XXmm with supports. The bridging may otherwise very well be too much to handle.

Each part has an additional depth offset of 0.1mm to account for drooping bridging or unclean support material removal.

3. Manual Filament Changes

If your printer can't do intricate inlays with the necessary precision, this route will still ensure you can print this model, as long as your printer supports Filament Change at Layer commands.

For the manual filament change route, here's what you do:

Sign Park_FilChangeAtLayer.stl
This part needs supports!

1. print the first layers for the protruding part in blue
2. print the next layers until the end of the sign itself in white
3. print the rest of the model (the metal pole piece) in silver

Sign Vac_FilChangeAtLayer.stl
This part needs supports!

1. print the first layers for the protruding part in black
2. print the next layers until the end of the sign itself in white
3. print the rest of the model (the metal pole piece) in silver
